[SOLVED] W3 not validating certs


i just had a check to my website i'm currently creating.

But when testing, i have this error :

I got the following unexpected response when trying to retrieve https://lib.est-chez.ovh/:
500 Can't connect to lib.est-chez.ovh:443 (certificate verify failed)

Can you see how you can do ?

Your server isn’t sending the intermediate certificate for Let’s Encrypt. Make sure to point your nginx configuration to fullchain.pem instead of cert.pem.

You can verify the fix using SSL Labs.


you’re right.

What is cert.pem used for ?

Some software expects the intermediate and server certificate in separate files. fullchain.pem contains both.
